Coding distortion for a G.711 codec. 1 40 (12/21/2005 12:38:45 AM) comp.dsp I have implemented a G.711 encoder and decoder over the StarCore 1400. I need to determine the distortion produced by the conversion of linear 16 bit samples to 8 bit non linear PCM (encoding) and back to 16 bi... tanmay

Filter design. #2 6 26 (12/1/2005 11:31:24 PM) comp.dsp I have to design a simple low pass filter (for audio) to reject frequencies beyond 3.6kHz. The design of the filter is quite simple. However, I want to know what affect the sampling frequency of the audio will ... tanmay

Polyphonic ring tone. 10 29 (8/8/2005 9:26:35 PM) comp.dsp Folks, I need to generate a simple polyphonic ring-tone, say like the one we have on old POTS telephones. I need to know the frequencies and also the cadencing information, e.g. 1 second of polyphonic tone fol... tanmay

Quantization of fixed point filter coefficients. 1 34 (7/20/2005 3:58:15 PM) comp.dsp This post is a retake on the 'quantization of filter coefficients' issue. Let me present the issue in the following. I have designed a filter (notch, cut-off 55.7Hz) which is a bi-quad. The transfer function... tanmay

DSP job opportunity. 0 39 (7/11/2005 4:35:30 PM) comp.dsp Folks, There is an opening for a "Sr Software Development Engineer" at Legerity, Inc in Austin, TX. (Yes, I work here.) Basic skills needed include DSP, fixed point algorithm implementation, audio signal proc... tanmay

FFT for the StarCore SC140 2 30 (6/1/2005 7:42:29 PM) comp.dsp Anyone know where I can download a library/function/API for fixed point FFT implementation over the StarCore SC140? T. ... tanmay

Antilog - base 10 34 49 (6/1/2005 3:53:51 PM) comp.dsp Hello, I am trying to compute the antilog of a fixed point number 'x' -> 10^(x), to be precise. I do not want to use a look-up table for the same. One way this can be done is to use the Taylor series expansio... tanmay

Upsampling revisited. 3 36 (5/12/2005 3:12:56 PM) comp.dsp Hello, I have some basic ideas related to upsampling to bounce off this group. I have a filter's transfer function, say H(z). I want to know what H(z^2) means. I know that I had asked a similar question on a... tanmay

Scaling in fixed point filter design. 6 30 (5/9/2005 3:26:23 PM) comp.dsp People, I am designing fixed point filters for processing audio signals and am faced with the following issue. I need to have the output within a range of +0.999969 and -1 or effectively 32767 and -32768 (ran... tanmay

Simulink: S functions 1 18 (5/2/2005 5:24:43 PM) comp.soft-sys.matlab People, I am developing a C-MEX file (S-function) for implementing fixed point filters and testing the same using Simulink. I have 16 bit signed data in 1.15 format. I wanted to know what data format I should... tanmay.zargar (33)

Multiplication not supported for int16 data types in Matlab. 8 30 (5/6/2005 4:10:07 PM) comp.soft-sys.matlab Hello, I came across a weird error in Matlab. It says that I cannot multiply two data types of int16 using the * sign. More specifically here is the error, along with the code I tried. >> a = int16(3); >> b =... tanmay.zargar (33)
